CGRNER-STAND FOR WEiGHENG StZALESQ SPECIFICATION forming part of Letters Patent No. 448,615, dated March 17, 1891 Application filed September 22, 1890- $erial No. 365,811. (No model.)

To aZZ whom it may concern.-

Be it known that I, ILtLvOit O. llEM, of Kansas OityflVyandotte county, Kansas, have invented certain new and useful improvements in Corner-Stands for lVeighingScales, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a parthereof.

My invention relates to improvements in corner-stands for weighing-scales; and it consists in the peculiarcombination and arrangement of the several parts, as will be fully described hereinafter, and particularly pointed out in the claims.

My object is to always present a full bearing-surface to the knife-edge, which is so arranged as to adjust itself to the bearing-surface during the oscillation of the same, caused by the adjustment on the platform of the article to be weighed.

Referring to the drawings which illustrate this invention, Figure 1 is a top plan view of my improved corner-stand, showingin dotted lines the position of the cross-tie I. Fig. 2 is a vertical section on line a; it of Fig. 1. Fig. Sis a vertical section on line y of Fig. 1. Fig. 4.- is a perspective view of the link which connects the swings and also carries the adjustable knife or bearing-point. Fig. 5 is a detail perspective view of one of the swings. Fig. 6 is a plan view showing the cornerstands connected by the cross-ties. Fig. 7 is a side elevation of the same with the platform secured thereon.

Similar letters refer to similar parts in all the figures, in which A represents the corner-stands connected by the cross-ties P, each of which ties is provided with an arm Q. The end or connecting bars R of cross-ties l are provided with the enlargements S, provided with the transverse notches or grooves l in their under surfaces. Ears U, depending from the lower surface of the platform Y, are rigidlysecured by the angular pins or rods T to the arms Q, near their union with the cross-ties P, to each of which one end of each of the arms is rigidly secured, the opposite end of the arm being notched in order that it maybe connected to a lever, (shown dotted at Q, Fig. (3,) which is in turn connected with a graduated beam,

as is well known, and need not be further illust *ated.

Transverse notches or grooves of bars R rest upon the upper sharpened edge 0 of knife N, which rests upon the convex surface of transverse extension or shoulder I of the link-plate I. The knife is withheldfrom longitudinal or lateral displacement, respectively, by means of side ears if, extending vertically upward from the linkplate l opposite each end of the knife N, and the vertical guide-lugs L on the inner sides of said ears K forming between them the grooves or pas-.

sages M, into which the knife is vertically inserted. The link-date I is provided on its under surface near each end with the grooves J, extending transversely across the entire width of the plate. These grooves, extending in a parallel direction with the grooves P, are V-shaped in end view and lit upon the knife-edge ll of the cross-bar G of each of the swings D, which are provided at their upper ends with arms E, extending in the same direction as the cross-bar G, said armsE being provided with the knife or sharpened edges F, which pivotally rest and operate upon the con cave upper surfaces of standards 13, extending vertically upward from the baseplate A of the corner-Stan d, which rests upon the ground.

The knives N are of such abridged length that they will oscillate and adjust themselves upon the convex bearings to the inclination of the bearing-surfaces I upon them with out becoming disengaged fromthe guide-slots M at either end, as will be readily understood.

The operation of my invention is as follows: The improved cornerstands are situated under the four corners of the platform, as shown, and the weight applied to the plat form causes, by reason of the two swings D, connected and operating together on separate but parallel bearings at the upper end of standards 13, a longitudinal movement of the connecting link-plate I and therefore of the knives N, which is an obvious advantage over the single-swing arrangement. The oscillation of the machine in the direction pa 'allel to the axis of the swings D causes the knives resting on the convex bearing-shoulders I to always present a full bearing-surface for the notches or grooves P, or, in other words, to

oscillate with the bearings, theknives always resting and bearing against the highestpoint of the notches or grooves P for their entire width, as will be readily understood.

Having thus fully described my invention, what I claim as new, and desire to obtain by Letters Patent, is-

1. The improved. corner-stand for weighingscales, consisting of the casting having the base-plate provided with two pairs of vertical extensions B, two parallel swings D, the connecting link-plate I, andadjustable knife N, substantially as described.

2. In acorner-stand for weighing-scales, the combination,-with a casting having a baseplate provided with integral extensions B, having the concave bearings in the upper surface, of the parallel swings D, connected by the link-plate I, substantially as and for the purpose set forth.

3. In a corner-stand for weighing-scales, the combination,.with two parallel swings G, having edged cross-bars, of a connecting-link having V-shaped notches in its lower face to receive the said cross-bars, as described.

4. In a corner-stand for weighing-scales, the connecting link-plate I, provided with the 7. The combination, with a platform, of

cross-ties at its opposite ends connected rigidly thereto, a tie connecting the said crossties, links I, having removable knives therein carrying the said cross -ties, and parallel swings carrying the said links, as described.

In testimony whereof I affix my signature in presence of two witnesses.
